ECU Elite 550
The Elite 550 is a compact yet powerful engine control unit (ECU), ideal for basic engine applications
ranging from 4 to 8 cylinders or 1 to 2 rotors. It supports both naturally aspirated and forced induction engines,
providing full control over fuel delivery, ignition, and boost levels. A solid, waterproof IP67-rated casing
protects the system from harsh environmental conditions.
The Elite 550 is now compatible with the new Nexus Software Programmer (NSP),
which offers an unprecedented level of functionality and intuitiveness in engine control management.
This advanced solution meets the needs of both tuners and racing enthusiasts worldwide.
